The UK and the single market

A key debate for some months has been the UK’s membership of the European Union. The debate has centred around the desire to return some powers back to the UK, but this has extended into the possibility of a referendum on our membership of the preferential trading area. So, let’s take a step back and consider why any country would want to be a member of a preferential trading area.

Preferential trading areas can be as basic as a free trading area or as advanced as a currency, or even political union. The eurozone is clearly a currency union, but the European Union, of which the UK is a member, is a common market. A common market has no tariffs and quotas between the members, but in addition there are common external tariffs and quotas. The European union also includes the free movement of labour, capital and goods and services. Membership of a preferential trading area therefore creates benefits for the member countries. One such benefit is that of trade creation. Members are able to trade under favourable terms with other members, which yields significant benefits. Countries can specialise in the production of goods/services in which they have a comparative advantage and this enables greater quantities of output to be produced and then traded.

Other benefits include the greater competition created. By engaging in trade, companies are no longer competing just with domestic firms, but with foreign firms as well. This helps to improve efficiency, cut costs and thus lower prices benefiting consumers. However, from a firm’s point of view there are also benefits: they have access to a much wider market in which they can sell their goods without facing tariffs. This creates the potential for economies of scale to be achieved. Were the UK to completely exit the EU, this could be a significant loss for domestic firms and for consumers, who would no longer see the benefits of no tariffs on imported goods. Membership of a preferential trading area also creates benefits in terms of potential technology spillovers and is likely to have a key effect on a country’s bargaining power with the rest of the world. As is a similar argument to membership of a trade union, there is power in numbers.

There are costs of membership of a preferential trading area, but they are typically outweighed by the benefits. However, estimates suggest that the cost of EU regulation is the equivalent of 10% of UK GDP. Furthermore, while the UK certainly does trade with Europe, data suggests that only 13% of our GDP is dependent on such exports. The future is uncertain for the European Union and Britain’s membership. There are numerous options available besides simply leaving this preferential trading area, but they typically have one thing in common. They will create uncertainty and this is something that markets and investors don’t like. Vince Cable warned of this, saying:

There are large numbers of potential investors in the UK, who would bring employment here, who have been warned off because of the uncertainty this is creating.

The impact of the UK’s decision will be significant and not just for those living and working in the economy. The world is no interdependent that when countries exist (or typically enter) a preferential trading area the wider economic effects are significant. While any change in the UK’s relationship with the EU will take many months and years to occur and then further time to have an effect, the uncertainty created by the suggestion of a change in the relationship has already sent waves across the world.
